Leak to dry to treated, one company in West Dulwich

West Dulwich is characterised by large Victorian and Edwardian villas, many converted into flats, alongside 1930s semis and mansion blocks near the station and Croxted Road. Original slate roofs, aging cast iron plumbing and rear extensions with flat roofs are common, and these older building elements are especially prone to hidden leaks as materials perish with age.

Common leaks in West Dulwich homes

Flat roof extensions over kitchens and bathrooms

Many West Dulwich villas have single storey rear extensions added over the decades, often topped with felt or GRP flat roofs housing kitchens or bathrooms. These roofs frequently develop splits or perished flashing where they meet the original brickwork, letting water track silently into ceiling voids and wall cavities long before any staining becomes visible inside the home.

Converted flats with stacked bathrooms

Large Victorian houses split into upper and lower flats around Rosendale and Croxted Road often have bathrooms stacked directly above one another. Failed shower seals, cracked grout or a slow leak from an upstairs waste pipe can seep through original timber floors and lath and plaster ceilings, causing damage to the flat below before the leak is ever noticed.

Ageing pipework in period plumbing systems

Properties near Dulwich Park and Alleyn Park retain original or early replacement plumbing runs, sometimes lead, galvanised steel or early copper, hidden beneath floorboards and within solid walls. Corrosion, perished joint seals and thermal movement cause slow escapes of water that soak into dense period masonry, spreading damage well beyond the source before it surfaces.

Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.

Tip: If your water meter ticks over with every tap off, or a wall or ceiling stays damp with no obvious cause, there is a hidden leak. Finding it early is far cheaper than repairing the mould and damage it leaves behind.
